Sealmaster N60 Seal

N60 is a combined fire and smoke seal for 60 minute, single action fire and smoke-resistant doorsets.

The N60 Intumescent Fire and Smoke Seal consists of an extruded aluminium alloy profile, having two reservoirs of Sealmaster intumescent material and a self-extinguishing, flame-retardant elastomeric blade.

In normal use, the elastomeric blade seals the gap between the door and the frame, and acts as an efficient draught seal. The seal is interrupted at the hinges and lock/latch plate positions, and protection at these points is provided by Sealmaster Intumescent Plugs.

N60 Intumescent Fire and Smoke Seal, with flame-retardant elastomeric draught/smoke blade insert, was tested by TRADA. Stability and integrity were retained for 71 minutes. N60 Fire and Smoke Seals have been tested and approved by Certifire to conform to BS476 part 22.
